• Ms. Finsch Tiscareno Associates Plan Check Number: B1801-032, First Review March 13, 2018 and details for the backspan connection should be submitted for review. It is recommended that the stability of the back-span consider Equation 16-10 with a 0.6-factor on the resisting weight (i.e., floor). See IBC Sections 107.2.1 and 1604.1. 17. Sheets S209a and S209b show steel HSS columns at Grids S-A/S-7 S-8.3 and S-C/S-7— S-8 supporting wood-framed construction. Calculations substantiating the design of the columns, foundations, and connections should be submitted for review. Details for the connections between the steel and wood framing should be included in the drawings. See IBC Section 107.2.1 and 1604.1. 18. Sheet S209a shows floor framing at Grid S-A— S-B/S-7— S-8 that supports a bearing wall and framing above. The plan also shows a bearing wall below at Grid A-A.7 that appears to bear on a PSL7 at Level 2 per Sheet S208a. Calculations substantiating the design of the floor framing should be submitted for review. See IBC Section 1604.1. 19.The structure includes GL3-1/8 along the corridors. See Sheet S202a for an example. The beams appear to require hangers similar to the North Building per Section 6/S402. The structural plans should be reviewed and revised as needed. See IBC Section 107.2.1. 20. Sheet S208a-SS shows a bearing wall at Grid N.1-1.6/NN.1-A.5 — N.1-B that is continuous to the roof, and supports substantial areas for Levels 3 and 4 and the Roof. The wall appears to bear on the Level 2 framing on Sheet S208a. Note that the Level 2 framing provides an indirect gravity load path through multiple beams. Calculations, including a deflection analysis, substantiating the design of the framing and connections, including posts and foundations, should be submitted for review. See IBC Section 1604.1, 1604.3, and 1604.4. 21.The structure includes prefabricated bolt-on decks on Grids S-A and S.1-3 at Levels 2, 3, and 4. See Sheet S208b for an example. Section 4/S404 provides a connection for the attachment of the decks. Calculations substantiating the connection should be submitted for review. See IBC Section 1604.1. 22. Section 12/S404 appears to show connections to support a roof structure. The location of this structure is not clear. The use of this section in the project should be clarified. Documentation substantiating the design of the roof, including the connections, should be submitted for review. See IBC Section 1603.1 and 1604.1. 23. Sheet S210a and S210b show single TJI210 joists at 12-inch spacing west of the shoreline. The maximum span is 16 feet between Grids S-7 and S-8. Structural calculation page SC132 requires two joists spanning at 16-inch spacing. Calculations substantiating the joist should be submitted for review. See IBC Section 1604.2. 24. Sheet S210a and S210b show PSL5-1/4 and PSL7 along the shoreline. Structural calculation page SC135 evaluates PSL5-1/4 beams for spans up to 18'-3". The following comments should be addressed: a. The typical frame size should be clarified. See IBC Section 1603.1. b. The spans exceed 18'-3"between S-1 and S-1.6. Calculations substantiating the beam should be submitted for review.
